The ABB 3AXD50000121014 is a wall-mounted drive in an R3 frame, sized for a 7.5 kW motor on 380-500 V three-phase supply. Normal-duty output is 14 A; heavy-duty use drops to 5.5 kW and 11 A. Light-overload use holds at 7.5 kW with 13 A output. The drive includes the control unit and communicates via CAN — no onboard industrial Ethernet.
Overload duty and thermal headroom
Three duty ratings let you match the drive to the load profile. Normal use (Pn 7.5 kW, In 14 A) covers constant-torque applications like conveyors. Heavy-duty (PhD 5.5 kW, IhD 11 A) handles higher starting torque or cyclic loads. Light-overload (PlD 7.5 kW, IlD 13 A) suits variable-torque loads like fans and pumps. Standby loss is 40 W; power consumption at rated load is 355 W. Apparent power output is 12 kV·A.
Environmental limits and mounting
Rated for ambient temperatures up to +55 °C and altitudes to 4000 m. IP21 enclosure with NEMA Type 1 — suitable for indoor, clean environments. Operating humidity spans 5 to 95% RH. Sound level is 57 dB(A). Wall-mounted only; the R3 frame keeps panel footprint manageable.
Onboard I/O includes 2 analog inputs, 2 analog outputs, 6 digital inputs, and 2 digital outputs. Communication is CAN only — no industrial Ethernet port. The drive includes a control unit and a lithium coin cell (CR2032, 220 mAh) for backup.
